# 时间书 vs 时间日志

The clearest difference is iOS requirement: 时间书 at 13.0 against 时间日志's 15. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 时间书 sells 4 one-off in-app purchases and 时间日志 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 14, 2026 and July 20, 2026 respectively.
